SHAPING MACHINE.

. Application filed September 19, 1927. Serial No. 220,419.

This invention relates tonew and useful improvements in a shaping machine.

One object of the invention is to provide a machine of the character described specially designed for the purpose of shaping units of cork, and the like, into spherical form, and thus adapting them to be used as floats for fishing tackle.

Another object of the invention is to pro- Vide a float making machine of the character described which is of simple construction, may be easily operated and which is very efiicient in use.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side elevation of the machine, partly in section.

Figure 2 shows a sectional view thereof taken on the line 2-2 of Figure 1.

Figure 3 shows an end view of the machine, partly in section.

Figure 4 shows a sectional view of an incomplete float, and

Figure 5 shows a side View of the complete float. 1

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numerals 1 designate the legs of the framework which are connected by the upper and lower longitudinal angle bars 2, 2 and 3, 3 and the transverse end braces 4, 4.

There is a drive shaft 5, mounted to rotate in suitable hearings on the lower cross bars 3, 8 and fixed on one end of this shaft there is a drive pulley 6 to receive a driving belt, not shown. Fixed on the other end of this shaft there is a small belt pulley 7 and the shaft 5 is extended beyond said pulley 7 and forms a support on which the feed lever 8 has a bearing. This feed lever extends approximately vertically and at its upper. end there is another belt pulley 9, aligned with the pulley 7 and operating over the pulleys 7 and 9, and driven from the formenthere is belt 10.

Mounted on the framework, and rotatable in the bearings 11, 11, there is a shaft 12 and fixed on said shaft, between said bearlngs, there is a drive pulley 13, adapted to receive a belt 13 by means of which'said pulley and the shaft 12' may be driven.

Fixed on one end of the shaft 12 and aligned with the belt'lO there is an abrading wheel 14 having a peripheral groove 15, lined with suitable abrading material.

This wheel 14 is surrounded by a hood 16 whose mouth 17 faces toward the belt 10 and opposite'said mouth the hood has a. conveyor chute 18 to be operatively con nected with a suitable suction device, or fan, not shown.

Fastened to the feed lever 8, opposite the wheel 14, and extending at right angles to said lever, there is a flange 19 over which the belt 10 rides and the opposite side'of the belt runs over an idler roller 20 adjustably mounted on the lever 8 and designed to hold said belt taut. I

In front of the shaft 12, and rotatably mounted in the bearings21, 21 on the framework, there is a shaft 22, fixed to one end of which there is an upstanding arm 23. R0- tatably mounted in the upper end of the arm 23 there is a spindle 24 having a free end which extends across in front of the abrading wheel 14.

The individual corks, as 25, to be shaped, are cylindrical in form, with an axial opening 26therethrough.

The cork to be shaped is fitted onto the free end of the spindle 24, said spindle extending through the axial opening 26.

The grip 27, carried by the upper end of the lever 8, may then be grasped and the lever 8 moved rearwardly carrying the belt 10' into contact with the cork 25 and forcing said cork into the groove 15 of the abrading wheel 14. I

The cork will be held firmly against the abrading material in the groove 15 by reason of the fact that the flange 19'backs the belt 10 opposite its point of contact with said cork. The belt 10 and abrading wheel 14 travel in the respective directions indicated by the arrows in Figure 1 and the cork will be gradually ground down to spherical form, forming the completed float 27 shown in Figure 5. The groove 15, of course may be of any other contour than that of a semicircular cross sectional form, as shown, and the finished float will have a corresponding form.

When the grip 27 is released the arm 23 will be retracted to carry the float out of contact with the abrading wheel by means of the pull spring 30, one end of which is attached to said arm 23 and the other end of which is attached to the framework in front of said arm.

The cuttings from the work will be carried off throughthe chute 18.

The shaft 22 carries a fixed cross arm 31, which has the adjusting screws 32, 32, threaded through the respective ends thereof and whose lower ends are adapted to contact against the framework to limit the range of movementof the arm 23 toward and from the abrading wheel.

It is obvious that mechanical changes may be made in the construction of the machine and equivalents substituted for the parts shown without departing from the principle of the invention and I hereby reserve the rightto make such changes and adaptations as may be found desirable, and which do not depart from the principle of the invention as comprehended within the scope of the appended claims.

What I claim is 1. A machine of the character described including a rotatable abrading member, a swingable spindle forming a work holder, a revolving belt mounted to oscillate and adapted to be moved into one position into contact with the work on said spindle, whereby the work is rotated and also moved into contact with said abrading member, said belt being movable into another position to release said work.

2. A machine of the character described including a rotatable abrading member, a swingable spindle forming a work holder, an oscillatable revolving belt adapted to be moved into one position into contact with the work on said spindle, whereby the work is rotated and also moved into contact with said abrading member, said belt being movable into another position to release said work, and a yieldable member normally acting to hold the work out of contact with said abrading member.

3. A machine of the character described including a framework, a rotatable abrading member thereon, a work holder. including a spindle movable into and outof operative relation with said abrading member, said spindle being provided to support the work to be operated on by said abrading member, a feed lever pivotally mounted on the frame work'and adapted to be oscillated toward and from the abrading member, a revolving belt mounted on said lever, said lever being movable into one position to carry said belt into operative relation with the work on said spindle whereby said work may be moved into operative relation with the abrading member and simultaneously rotated.

4. A machine of the character described including a framework, a rotatable abrading member thereon, a work holder including a spindle movable into and out of operative relation with said abrading member, said spindle being provided to support the work to be operated on by said abrading member, a feed lever pivotally mounted onthe frame work, a revolving belt mounted on said lever, said lever being movable into one position to carry said belt into operative rela tion with the work on said spindle whereby said work may be moved into operative relation with the abrading member and simultaneously rotated by the frictional contact of the belt therewith, and a yieldable member normally holding the spindle, and the work thereon, out of operative relation with said abrading member.

5. A machine of the character described including a frame work, a rotatable abrading wheel thereon, a pivotally mounted arm forming a spindle holder, a spindle on said arm adapted to receive the work, said arm being movable into operative relation with said wheel, means normally holding said spindle out of such operative relation, a pivotally mounted feed lever, a revolving belt thereon means for regulating the tension on said belt, said lever being movable into one position to carry said belt into frictional operative relation with the work on said spindle, whereby said work is rotated and simultaneously moved into operative relation with the abrading wheel.

6. A machine of the character described including a framework, a rotatable abrading wheel thereon, a work holder mounted on the framework and movable into and out of operative relation with said wheel, means for rotatably supporting the work on said holder, means for rotating the work on the 1 said holder by frictional contact therewith and for simultaneously moving said work into operative relation with said abrading wheel, said work rotating and moving means comprising a revolving belt and a pivotally mounted support on which the belt is mounted.
